The Suprema, with a permanent president of its own, was evidently well fitted to encroach on the functions of the inquisitor-general and, as policy varied with regard to this presidency, it is perhaps worth while to follow such indications as we can find with regard to it. In 1516 Martin Zurbano was president of the supreme Councils of both Castile and Aragon and, in the interval between the death of Mercader and the accession of Cardinal Adrian, he acted as inquisitor-general of Aragon.[427] In 1520, when Charles at Coruña was departing from Spain, he appointed Francisco de Sosa, Bishop of Almería, as president. In 1522, Cardinal Adrian on August 5th, the day of his departure from Tarragona for Rome, appointed Garcia de Loaysa, the future inquisitor-general, president of the Councils of both Castile and Aragon.[428] It was inevitable that questions should arise as to the comparative standing of such an official and the inquisitor-general. Sosa, as president, had a salary of 200,000 maravedís, while Adrian as inquisitor-general had only 150,000, the same as the other members of the Council.[429] This implied superiority and it was evidently necessary to enforce subordination as when, in 1539, Cardinal Tavera was made inquisitor-general and Fernando Valdés president, the latter was told that he was not in any way to modify the orders of the former. So when, in 1549, Valdés succeeded Tavera and Fernando Niño, Bishop of Sigüenza, became president, Charles V wrote to him from Brussels, March 26th, that he was to obey the instructions given to Valdés on his accession.[430] It was doubtless found that this duplicate headship led to trouble, and the position of president was allowed to lapse for, in 1598, Páramo tells us that the inquisitor-general was president.[431] In 1630 Philip IV proposed to revive it under the title of governor of the Suprema, but the Council protested, arguing that it had from the beginning functioned successfully without such a head; if the office had no special prerogatives, it would be superfluous; if it had, there would be collisions with the inquisitor-general; in either case, the innovation would be regarded by the public as evidence that the Council needed improvement.[432] This may have postponed but did not prevent the creation of the office for, in 1649, we find a president acting.[433] It was probably soon discontinued for, in some lists of members about 1670, none is designated as president and if, in 1815, there is one found occupying the seat of honor as dean, he was probably only the senior member.[434]
